I think the official USGS estimate for recoverable oil in the Bakken is about 3 billion barrels, based on an old study; I think the last study was done in 2008, but I've lost track of a lot of this stuff. Hardly matters any more, does it?
Continental Resources is pushing the envelope, estimating as much as 24 billion bbls recoverable oil in a trillion-barrel original-oil-in-place shale reservoir.
According to Fox Business, NDIC puts the number at 6.5 billion bbls recoverable oil. To date, slightly less than one-fourth billion bbls have been recovered. So when four times the current total produced has been shipped, the Bakken will still be less than a billion bbls recovered. Then, only 5.5 billion more bbls to go ... and that's the NDIC estimate. As noted above, Harold Hamm suggests 24 billion.
